I work on an iMac at home, and nearly every day I get shut out of Facebook or Twitter on Firefox or Safari. Firefox delivers a "This Connection is Untrusted" warning that says that Twitter has an untrusted security certificate, and Safari renders a similar security certificate error.
This happens when I leave either Facebook or Twitter logged on for an extended time, and the only remedy that I have figured out is to clear the history and restart the computer.
I never have this problem with the Dell on my desk at work, so I assume that the problem has something to do with the iMac rather than with Facebook or Twitter.
Is there something about the iMac's security settings that needs adjustment? I welcome suggestions from Apple fanciers.
